The future v1.0.0 will bring some breaking changes, this guide will help you to prepare for the next major version.

Before upgrading​

  • If you run Docker, it is advisable to use the 0.x tag instead of latest. You will be able to decide when you want to upgrade, especially if you are updating containers automatically.
  • Backup your database.sqlite. You can find it in the configuration directory, by default:
    • on Windows: %USERPROFILE%/.komga/database.sqlite
    • on Unix: ~/.komga/database.sqlite
    • on Docker: in the directory you mounted as /config

Breaking changes​

  • The minimum Java version required will be Java 17:
    • If you run Komga using the jar, you will need to make sure your Java version is sufficient by running java -version.
    • If you run Komga using Docker, you don't need to do anything.
  • The hashing algorithm for files and pages will change. Previous hashes for files and pages will be deleted. On startup, if hashing is enabled, Komga will re-hash files and pages using the new algorithm.
  • The default port will be changed from 8080 to 25600:
    • If you use Docker, you will need to update your container or compose configuration to expose the new port.
    • You may need to adjust your reverse proxy settings.
    • You can still change the port through configuration.
